Cellular devices consisting of two sets of strips of heavy paper stock, crossing each other and interlocked, known as partitions or lillers, are made on automatic machines that punch the required notches into sheet stock, cut 'the stock into strips, and assemble the completed strips. When it is desired to change the cross dimensions or the height of the cells, it is a tedious operation to adapt the machine to the new size of` device, requiring substantially a reconstruction of parts of the machine.

The object of the present invention is to make it possible quickly and easilyto effect the necessary changes in the machine for producing devices of various kinds; or, in other words, to make the machine to a large extent, at least, inherently adjustable.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of itspobjects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a side View of'a machine embodying the principles of my invention; Fig. 1a is a section, on a larger scale than Fig. 1, through the arm that carries the pawl which turns the feed rolls at the front end of the machine; Fig. 2 is a side View, showing the opposite side from that appearing in Fig. 1; Fig. 3 is atop plan view, on a larger scale, of

The machine illustrated in the drawings comprises, a sturdy base 1 upon each end vof which is fixed a suitable frame, indicated at 2 and 3. The frame 2, which may be said to be at the hack of the machine, supports mechanisms for suitably punching a sheet to form the notches in one set of partition strips, and slitting the sheet into ribbons each of which consists of a series of partition strips arranged end to end. The frame 3 supports mechanisms for punching transverse rows of notches in a second sheet, cutting one partition strip after another from the end of that sheet, and pressing each strip f down into interlocking engagement with strips that have been formed at the rear end of the machine andcarried forward. The first sheet enters the machine in a horizontal condition and ribbons into which itis slit are twisted so that when they reach the front end of the 100 machine they stand on edge. The second sheet is carried down from the top at the front end of the machine in a vertical condition, so that each partition strip produced at thel front end is in the proper position to be pushed down into engagement with the stripsl advancing from the rear. This general description applies as well to the old type of machine as it does to my improved machine, but is necessary for an understanding of my invention.

I shall first describe the rear end of the ma chine. Projecting rearwardly from the frame 2 is a suitable table 4 provided on top with laterally adjustable guides 5, 5 of any usual or suitable construction. The sheet A, properly positioned in the lateral direction by the guides 5, passes over the table and through a punching mechanism. The punching mechanism comprises dies, over Which the paper passes, and vertically movable punches above. In the drawings I have disclosed a machine with parts adapted to make partition devices in which there are five strips in each set, but it will of course be understood that partition devices containing any desired number of strips may be formed. The dies, as perhaps best shown in Figs. 8 and 9, comprise flat blocks 6 wider at the bottom than at the top and provided with long wide slots or openings 7 in the center. The actual working faces of the dies are preferably hard steel plates 8. For convenience in manufacture these plates are made in two sections divided along a' line that cuts through a slot 9 of the size and shape'of the slot or notch to be cut in the sheet. The two sections of each plate may conveniently be secured to the corresponding block by means of countersunk screws 10. The guide blocks are mounted in a suitable bed member 11 having in the top thereof an undercut groove 12 extending from lend to end of the same; the groove being of such a size and shape that the die blocks are a sliding fit therein,the upper surfaces of the die blocks being flush with the top of the bed. An auxiliary groove 13, extending the length of the main groove, is

' cut into the bed from one side of the main groove. In this auxiliary groove is a bar 14 whose inner side is shaped to fit against the adjacent sides of the die blocks. A number of set screws 15 extend through the side of the bed member into engagement 'with thc outer side or edge of the bar. It will be seen that when the set screws are tightened the die blocks will be firmly held in place. Upon loosening the set screws, the die blocks are left free to be moved lengthwise of the bed. The bed is fixed to a part of the frame 2 by means of suitable screws 16, or otherwise. Furthermore, the bed is provided .with a long slot 17 underneath and in registration with the slots in the die blocks. The slots 7 are preferably wider than the slots 9. Therefore the little pieces that are punched out of the sheet may any desired form.

drop down freely through the body portions of the die block and through the bed. The bed is provided with a suitable scale 18 along one side of the groove 12, by means of which scale the die blocks may-be accurately adjusted relatively to each other.

The punches 2O that cooperate with the dies just described may be of the usual or 'Ihe upper end of each punch extends into and is fixed to a suitable supporting block 21. Above, and pinned to each block 21, by means of onel or more pins 22, is a second block` 23.4 When the parts are assembled, each block 2l and the corresponding lblock 23 act as a single element which is held in a guiding support so as to be slidable in a direction parallel with the sliding movements of the die blocks. In the arrangement shown, the immediate supporting and guiding structure for the punches is a member 24 in the form of an inverted channel of the proper size and shape to receive the blocks 21 and 23. The blocks are held up by means of bars 25 secured by bolts 26 or otherwise to the bottom edges of the flanges of the member 24 and projecting a short distance into the trough of the channel so as to underlie the blocks 21. The member 24 is fastened to the underside. of a heavy cross beam 27 by means of bolts 28, or otherwise. lAt its ends the beam 27 has long vertical journal bearings 29 that fit slidably on stationary vertical posts or columns 30 risingfrom the frame 2. .The beam is moved up and down on these columns, by any suitable mechanism, so as to move the punches up and down. It will be seen that when the punches are down in the dies, as shown in Fig. 6, and the set screws l5 holding the die blocks in place are loosened, any movement of the die blocks from or toward each other will be accompanied by the corresponding shifting of the punches, and vice-versa. Therefore, if means are provided for adjusting either the die blocks or the punches, both.

punches. There are two horizontal shafts 31 and ,32 extending through all of the blocks 23. These shafts are geared together by means of suitable gear wheels 33, so that if one rotates the other will rotate at the same speed in the opposite direction. On one of the shafts is a bevel gear 34, meshing with a complementary bevel gear 35 on the lower end of a vertical shaft 36 provided by the beam 27. On the upper end of the shaft 36 is a hand wheel 37 by means of which it may be turned.

Assuming that the punching mechanism is set as illustrated in Fig. 6 and that it is desired to increase the distances between the punching mechanisms, it will be seen that the central punch and die may be left sta-
